"Remember, no one must be told that the doctor is coming here; and he himself must be sworn—sworn to secrecy. Promise me you will not tell a soul you have seen me, not a living soul." She was labouring under strong excitement, and it alarmed Christina to notice how the whiteness of her face had extended to her very lips, and what black shadows of suffering and fear lay under her eyes.
"Promise," she repeated, her grasp tightening on Christina's shoulder.
"I—promise," Christina answered slowly. "I will not tell anyone that I have seen you, or what you have said to me; and I will—do as you wish about the doctor."
Having received the girl's assurance, the woman drew back from the cart, and stood watching it retrace its way up the hill, her hands wrung together in anguish, her dark eyes wide with pain.
Baba had been a silent spectator of the strange little scene, understanding very little of what passed between her two elders, but watching the face of the beautiful stranger with an intent scrutiny, curious in one so young.
"That was a beautiful Princess," she said, after the cart had driven a short distance. "Baba hopes the Prince will come soon, and take her right away."
"Perhaps he will," Christina answered absently, relieved that the child had woven the strange lady into a fairy tale, thus obviating the possibility that close attention would be paid to remarks Baba might make about their encounter with her; and speculating vainly over all that she had just heard and seen, and over the striking personality of the woman who had commissioned her to do so strange an errand.
Resourceful as nature and necessity had made her, Christina was nevertheless a little puzzled to think how she could make enquiries about a doctor, without betraying what she had been especially conjured to keep secret; but during the drive home her plans were matured, and, having reached the farm, and put Baba into her cot for her afternoon nap, she went to the kitchen in search of Mrs. Nairne.
That worthy dame was engaged in making scones for tea, and turned a flushed but kindly face to Christina, who had already won her heart.
"Well, missy, you and the precious baby's had a nice drive; and I'm sure you're wise and right to take her out early, in the sunshine, and let her rest a bit before her tea—a prettier baby never was."
